Clayton, 28, had 221 receptions for 2,936 yards and 10 touchdowns in six seasons with Tampa Bay. Those are solid numbers but not nearly what many projected after Clayton caught 80 passes for 1,193 yards and seven touchdowns as a rookie in 2004.

Clayton now has three days of practice to get ready for this weekend's game against the Jaguars. With Hakeem Nicks and Steve Smith out of action, it's likely he'll dress for the game. How much time he gets and how effective he can be remains to be seen.

Clayton had eight catches for 88 yards in three games with the UFL's Omaha Nighthawks.

It's been widely reported the UFL charges a $150,000 "transfer fee" to the NFL team that signs one of their players to an active roster. But as the Daily News reported earlier, that fee only applies to players who have been on a UFL roster for four weeks or more. Clayton was with Omaha for only three weeks, so the Giants won't have to pay the fee.
